Abstract: The lightweight columbarium comprises a rigid frame made of a frame material, a number of decorative panels made of a decorative panel material, panel attachments for attaching the decorative panels to the rigid frame, and an enclosure defined within said decorative panels and said frame, for receiving a funeral urn. The frame material is less fragile than the decorative panel material and allows the frame to provide structural rigidity to the columbarium at less weight than if only the decorative panel material were used. The columbarium may be transported on a ritual transporter comprising a columbarium bed for carrying the columbarium and handles attached to the columbarium bed for transporting the transporter. The columbarium may be stored in a crate comprising a rigid protective shell attached to the columbarium externally thereof for protecting the columbarium against impacts; and an opening provided in the protective shell that is aligned with the bottom of the columbarium.
